Do you know retinol?
Retinol, also known as vitamin A1, is a derivative of vitamin A. Vitamin A is not a single compound but a series of retinol derivatives, including retinol, retinal, retinoic acid, retinyl acetate, and retinyl palmitate.
Retinol is a fat-soluble vitamin found in animal foods as a free aldehyde or ester, and is abundant in fat, protein, milk, and liver. Plants do not contain vitamin A, but they do contain a precursor of vitamin A (provitamin A), found in vegetables such as carrots and tomatoes. After absorption by animals and animals, it is converted into vitamin A. Retinol is essential for human growth, development, reproduction, and cell membrane stability, and plays a crucial role in vision. Retinaldehyde is constantly metabolized and consumed in the body, requiring timely replenishment through the oxidation of vitamin A. Vitamin A is crucial for the normal structure and function of cells. Deficiency can lead to dryness and inflammation of the conjunctiva and cornea, and even blindness. It can also damage the respiratory epithelium, predisposing to respiratory infections, hair loss, and developmental delays in infants.
Retinol, a nutritional supplement, is a fatty oil or concentrate derived from the liver and pyloric sac of aquatic animals. Fresh fish liver and pyloric sac are pulverized and then added with 1-2% sodium hydroxide solution to a pH of 8-9. Retinol can be used in sausages, margarine, bread, dairy products, juice powder, peanut butter, and more. Retinol not only promotes collagen production but also significantly improves the appearance of photoaging, fine lines, wrinkles, and hyperpigmentation.

TEST REPORT
Retinol Properties
1.Stability
Retinol has five double bonds, many of which are conjugated. This makes it chemically active and easily degrades into inactive substances. Oxygen, low pH, sunlight, and temperature accelerate its decomposition or isomerization reactions, affecting the stability of retinol products.
2. Irritation
Retinol must be converted to retinoic acid within cells to be effective. Retinoic acid (retinoic acid) is a pharmaceutical drug and is often used in acne treatments. Research has shown that different skin types have varying tolerances to retinol, potentially causing discomfort such as redness, flaking, and pain. Therefore, products containing retinol can be somewhat irritating to the skin.
Retinol's Physiological Functions
Maintaining Vision: It is the raw material for synthesizing rhodopsin, which is found in the retina and is essential for night vision. A deficiency can lead to night blindness.
Promoting Growth and Development: It plays a role in the development of bones, teeth, and the reproductive system. A deficiency can affect children's growth and reproductive health.
Protecting the Skin: It promotes skin cell renewal, enhances skin elasticity, regulates oil secretion, improves dryness and roughness, and has antioxidant properties, slowing down skin aging.
Boosting Immunity: It improves the body's resistance by regulating immune cell function. A deficiency can increase the risk of infection.
Specific Skincare Benefits of Retinol
① Promotes Metabolism
Research has shown that retinol helps reduce inflammation, protects the epidermis and mucous membranes from bacterial invasion, regulates skin cortical metabolism, reduces the likelihood of inflammation, and promotes skin cell regeneration, replacing aging cells with healthier new ones. It also enhances keratin metabolism, tightening the formation of new cells and improving pore size.
② Improves dull skin tone
Retinol promotes keratinocyte metabolism, lightens pigmentation, and provides antioxidant benefits. It significantly inhibits melanin catalysis and hinders melanin formation, causing existing keratinocytes to shed along with melanin, addressing pigmentation and effectively brightening the skin.
③ Controls oil secretion
Retinol influences the maturation of sebaceous gland cells, reducing oil secretion. This reduces facial oil production and significantly improves pore-related issues such as closed comedones, acne, blackheads, and enlarged pores.
④ Enhances skin immunity
Low doses of retinol stimulate the skin's own immune system, regulating its immune function and promoting a healthy complexion from the inside out.
⑤ Antioxidant and Anti-Photoaging
Retinol can prevent abnormalities in the biochemical composition and morphological structure of dermal connective tissue, stimulate the synthesis of extracellular matrix proteins, accelerate the formation of new connective tissue in the upper dermis, and increase the tensile strength of wound sites. It promotes skin cell proliferation and collagen synthesis, filling wrinkles and sagging areas, thereby firming the skin.
In addition, retinol can inhibit the activity of two matrix metalloproteinases, MMP1 and MMP9, which are over-stimulated by ultraviolet light. This reduces damage to collagen fibers, inhibits photoaging, and prevents the appearance of wrinkles and sagging.
Applications of Retinol
Skin care
As a core anti-aging ingredient, it's used in serums, face creams, eye creams, and other products to minimize fine lines, improve photoaging, and enhance skin firmness and elasticity. It's also used in acne treatments and oil-control products to help unclog pores and reduce the appearance of acne. In functional cosmetics, it's used to improve uneven skin tone, fade dark spots, and brighten overall complexion, and is commonly found in spot-lightening serums and rejuvenating masks.
Pharmaceuticals
It's used to treat acne (such as retinoids) and in prescription dermatology medications for psoriasis and certain keratinization disorders.
Scalp Care
Some hair loss prevention or scalp regeneration products are also experimenting with retinol to promote scalp health and stimulate hair follicles.
Body Care
It's gradually expanding into products like neck creams and body lotions for overall anti-aging and skin texture improvement.
